I have a well, and just installed 2 new hot water tanks (50 gallon each). The system, besides being on a well, has a hot water recirculating line, with a grundfos pump, and a checkvalve (on the recirc line only).
My cold water line, traced back to the well, has a main shut off valve, wiring for the well pump, and a "dial/degree" shut off valve where the water line enters the house. I see no checkvalves or other items in the line.
Do I need to install a thermal expansion tank ? If so, the manufacturer instructions all indicate that the tank should be placed between the tank shut off valve and the tank itself. However, my shut off valve is located only about 5-6 inches from the tank. That leaves me a narrow spot to install the tank. Indeed, that area of the cold water inlet line often gets warm from the heat of the tank. Is it safe to install the tank at that spot? I can cut into that 3/4 inch pipe, place a tee, and extend a pipe out, and put a 90 degree with a female end and strap to the ceiling.
Is it safe to install a thermal expansion that close to the top of the tank itself? Thank you
